This book systematically summarizes the latest research findings on high-speed railway track dynamics, made by the author and his research team over the past decade. It explores cutting-edge issues concerning the basic theory of high-speed railways, covering the dynamic theories, models, algorithms and engineering applications of the high-speed train and track coupling system.

Presenting original concepts, systematic theories and advanced algorithms, the book places great emphasis on the precision and completeness of its content. The chapters are interrelated yet largely self-contained, allowing readers to either read through the book as a whole or focus on specific topics. It also combines theories with practice to effectively introduce readers to the latest research findings and developments in high-speed railway track dynamics. It offers a valuable resource for researchers, postgraduates and engineers in the fields of civil engineering, transportation, highway &railway engineering.

The first book to comprehensively cover the theories, models, algorithms and engineering applications of high-speed railway track dynamics Covers highly efficient numerical methods for non-linear dynamic analyses of the vehicle and track coupling system Offers several engineering application examples involving high-speed railway track dynamics in railway infrastructure Includes supplementary material: sn.pub/extras
